I have been producing sustainable structures since 1997, on my own projects and as a consultant, designer and builder, in Wales and in Spain. Originally a photographer, this led to a focus on creative functional structures, after a long process of changing my own living environment. I explore how sites can provide choices in materials for structures, which can reduce the carbon footprint of a build substantially, potentially to zero. There are many clues in vernacular buildings, waste streams and in the ground beneath our feet. I have developed a reputation for creating structures from whatever is to hand and have a wealth of eclectic experience, that I use to unpick social and practical problems. 

I began ‘Salad Workers in Spain’ in 2014, a social justice project that built compost toilets and edible gardens with volunteers in migrant camps in Almería, Spain. Now, resettled in Wales, I co-founded and project manage ‘Incredible Edible Porthmadog’ (since 2016) and teach in local and waste materials. I have articles published in Spain and in the UK on sustainable building methods and agriculture in Almería.

Solid waste as a construction material solution

Solid waste (SW), is now commonly recognised as a global threat that is unconstrained by boundaries and new international solutions/agreements are called for (Borrelle et al., 2017). Ocean clean-up projects are collecting plastic which will add exponentially to land based waste. Waste material could be viewed as a resource, if it can be organised, repurposed and used; for example, glass bottles, cans, plastic bottles or tyres. In addition, in areas where conflict or disaster has occurred, building materials can be scarce and using waste can be a solution, or a part of preparedness. Studies examine waste management in various scenarios; post conflict (Calò and Parise, 2009; Karnasena, 2015) developing countries (Henry et al. 2006; Marshall and Farahbakhsh, 2013), recycling issues (Tam and Tam, 2006), waste placement alternatives (Riley, 2008) and new definitions of the waste problem (Tong and Tao, 2016; MacArthur, 2017). Few academic studies explore proposals for direct reuse of waste material.
